The relative importance of environmental conditions and stock abundance in determining the productivity of fish stocks has been a subject of an on-going debate. The controversy can be formulated as four competing hypotheses: ...

Until relatively recently, fisheries resources were managed as single homogeneous units and fisheries management conveniently ignored the presence of spatial heterogeneity in stocks. In nature, species are neither distributed ...

This work explores (1) the potential for using marine reserves to manage data-poor fish populations, (2) the potential for marine reserves to influence the performance of commonly used stock assessment approaches relative ...

The research in this Ph.D. dissertation focuses on the relationship between fishery-dependent catch-per-unit-effort (CPUE) and abundance and how its use when assessing and managing fisheries may be affected by some of its ...
